3 Claims. (Cl. 93--3) This invention relates to an apparatus for and process of making lipsticks or like articles in pencil form.

The article produced by this improved apparatus and process consists generally of an outer covering or sheath which may be in the form of a rolled paper tube, and which encloses a core or filling of lipstick substance. When a paper covering or sheath is used it is adapted to be sectionally unrolled or removed to expose the core of lipstick substance in the manner that the wellknown Blaisdell or paper-covered pencil eX- vposes its lead. The core or filling is composed of a relatively soft, easily fusible substance which is poured into the covering or sheath While in a molten condition. Upon cooling, it solidifies.

In manufacturing pencils of the paper-covered or Blaisdell type, the lead or other Writing material generally employed is fusible only at a relatively high temperature and such lead or core easily permits the paper wrapping or sheath to be formed by being wrapped directly about the core. A core or lling of a material such as is used for lipstick purposes becomes molten at a relatively low temperature and since the sheath is formed by rolling up a paper sheet by heated rollers, eorts to form the sheath by wrapping it directly about such lipstick material, caused the lipstick material to melt or liquefy and run out of the sheath. v

The object of this invention is to providean apparatus and process for manufacturingA Alipsticks or like articles wherein the paper covering or sheath is produced in tubular form over a solid, removable core, the core being then removed and the sheath lled with molten lipstick material, which, after being poured into the tubular covering or sheath solidifies to form a solid core or filling. This apparatus and process are particularly useful for the production of lipsticks made in pencil form, crayons, colored pencils and similar articles, where the filling or core is of relatively soft, easily fusible material.

Speciiically, the invention resides in a means and process of first forming the tubular rolledpaper sheath; in supporting it in a position to permit the lling material or core to be poured into it, and in maintaining the iilling material in a iiuid condition during the pouring operation by the application of heat.

Since the lipstick material used for forming the core or lling solidiiies rapidly upon cooling, it is necessary that such material be constantly maintained under a sufficiently high temperature to keep it fluid until it has reached its actual paper from which one of the tubular sheaths is position of deposit within the sheath. The sheath being preferably composed of paper cannot be heated to insure the easy flow of the molten filling material within them. Accordingly, to insure a complete and positive filling of the sheaths, I utilize heated tubes which are inserted into the sheaths, and pour the heated liquefied lling material through these tubes and into the sheaths, the tubes being withdrawn from Within the sheaths as fast as the sheaths are filled. 65

In the preferred embodiment of my invention disclosed in the accompanying drawings, Fig. 1 is a plan view of the paper sheath showing how the same is formed by being rolled on a removable solid core or former; Fig. 2 is a plan 70 View of a lledsheath, with a part of the sheath broken away to disclose the filling material Aor core; Fig. 3 is a plan View of portions of the apparatus for filling the sheaths; Fig. 4. is a vertical sectional view through the'supporting means for the paper sheaths, showing several sheaths held in position ready for lling; Fig. 5 is a similar view, showing the sheaths inthe act of being filled with the liquefied iilling material; Fig. 6 is a View showing the relative positions of the parts immediately upon the completion of the filling operation; Fig. 'l shows the filled sheaths held in their supports'and ready for removal; and Fig. 8 is a vertical sectional View through the lower support, the upper sup- 85 port, the lling tray and one of the lling tubes showing the tube at the beginning of its filling operation.

In the drawings, 10 indicates the sheet of made. This paper sheet is similar to thosefrom "which pencil sheaths on the paper-covered Blaisdell pencils are made. The sheet 10 is scored at spaced intervals at 11, these scored lines permitting sectional removal of the sheath by 5 an unwinding action as is clearly understood. The spaced perforations 12 permit the sections defined by the lines 11 to be easily torn from the rolled sheath.

If desired, the scorings 11 may be spaced sufli- '-1'00 ciently close so that each unwrapping will uncover only a suiiicient amount of the core for one application to the lips. Thus, a fresh section of the core would be uncovered only when Y needed, the remainder of the core being covered 105 and kept clean and sanitary.

The first step in the production of the article consists in forming the paper sheet 10 into a tubular sheath, which may be accomplished in' a number of ways, one of which consists in rolln@ Vet() ing the sheet upon a. solid removable core or mandrel 13 and adhesively securing down the end 14 of the sheet in the well-known manner to maintain the sheet in its rolled condition. The rolling of the sheet 10 in this way results in the formation of the conical end 30 on the finished tubular sheath in a manner well understood in this art. The solid core 13 is then withdrawn from the sheath, leaving the sheath in the tubular form shown at 15 in Figs. 4 to 8 inclusive.

The apparatus for simultaneously filling a number of the sheaths is shown in plan in Fig. 3. It is provided with a lower xed supporting plate or base 16 having a plurality of spaced conical recesses 17 into each of which the conical end 30 of a sheath Will't with suicient snugness to cause the sheath to be held in a vertical or upright position, as shown in Fig. 4. As each of the recesses 1'7 is closed at its lower ends the insertion of the end of a sheath into it acts to close the lower end of the sheath so inserted. A tray 18 provided with a plurality of holes 19, corresponding in number and alignment to the recesses 17 in the base, fits over the upper portions of the sheaths as shown in Fig. 4, so that the sheaths when ready for lling are supported in upright, parallel relationship between lthe base plate 16 and the upper support or tray 18 as clearly shown in Fig. 4.

A section of the lling device is shown in detail in Fig. 8. The lling device is provided with a shallow tray 20 having a plurality of holes 21 formed in its bottom. Located in, and extending downwardly from each of the holes, is an elongated metal filling tube 22, one of each of these tubes being adapted to be inserted within each o1" the sheaths 15, while the sheaths are supported as shown in Fig. 4, and the molten -material 23 is caused to descend through the tubes into the bore of each of the sheaths in the manner shown in Figs. 5, 6 and 8. Since it is necessary to maintain the filling material in a iiuid condition during the filling operation by a constant application of heat, the tray 2,0 is heated by any suitable means, such as an electric heating device 24 operating upon the base or bottom of the tray. This heating device may also serve to heat the tubes 22 so that the iilling material will not solidify during the illing operation. Thev tubes 22 may also be heated by a supplemental heating device if more heat than can be conveyed by the heater 24 is required.

The operation of filling the sheaths with the lling material 23 is shown inrdetail in Figs. 5 to 7 inclusive. The first step is to insert the heated iilling tubes 22 within the sheaths 15 While the sheaths are held in their upright or vertical positions and are supported by the members 16 and 18 as shown in Fig. 5. The tubes 22 are inserted for substantially the full length of the sheaths. The filling material 23 in a heated, fluid condition is then poured in the tray 20 and it flows downward through the heated tubes 22 into the sheaths. The tubes 22 are gradually Withdrawn from Within the sheaths as fast as the liquid filler flows into and lls the sheaths. This lling operation continues until the sheaths are completely lled as shown in Fig. 6, by which time the tubes 22 have been completely withdrawn. Any excess lling material flowing out of the tubes 22 is then caught by the tray 18 as shown at 31 in Fig. 6. The filling material solidii'ies promptly. after being poured into the sheaths, whereupon the upper sheath-supporting tray 18 is forced downwardly until it reaches the base plate 16, as shown in Fig. '7, permitting the lled sheaths to be easily withdrawn.

What I claim is:-

1. An apparatus of the class described comprising a base provided with a plurality of spaced recesses for receiving the ends of a number of sheaths to support said sheaths in a substantially vertical position and to close the lower ends of the same, a plate having a plurality of openings extending through it into which the upper ends of the sheaths supported by the base fit, a heated container for holding a molten filling material, a plurality of heated tubes extending downwardly from said container and adapted to be inserted into the supported sheaths and withdrawn from within the sheaths as said sheaths are lled with the molten filling material ilowing through said tubes from the container, the openings in the plate permitting the plate to be brought downward to rest on the base after the sheaths have been illed so that the filled sheaths can be removed. g

2. The process of making lipsticks in pencil form consisting in rst spirally forming a tubular paper sheath about a core from a blank having parallel weakened lines forming strips with the strips overlapping when spirally wound on the core, then removing the core and `then pouring molten lipstick material into the sheath.
